I think Lafontaine and Mogilny in 1992-93 was a mutually beneficial partnership between two players with absolutely incredible talent.
In the case of Lafontaine, Buffalo represented a breath of fresh air. He was a frustrated player on the Island. And nobody could blame him. In those last three seasons, the lack of talent on Long Island was disturbing. Sure, they made the playoffs in 1989-90, but there were two reasons for that. Pat Lafontaine carried the team on his back. And the Patrick Division was truly pathetic that year. For that season, it supplanted the Norris as the worst division in hockey.
Lafontaine just didn't have talent around him. It's hard to put up assists when your wingers are David Volek, Mikko Makela, Alan Kerr, a young Derek King, injury-prone Pat Flatley and past-his prime Don Maloney. It's remarkable that he did what he did with the talent around him. He slumped badly late in 1990-91, and everyone knew that it was protest play. He wanted out.
The moment he arrived in Buffalo, he showed the hockey world what he could do with talent around him. Put Lafontaine on a power play with Hawerchuk at the point, Andreychuk in front and Mogilny to take passes. Put him at 5-on-5 with Mogilny. The only thing that could stop him was a Jamie Macoun high stick.
Mogilny played with a level of passion in the second half of 1991-92, and in 1992-93, that he rarely showcased again. Yes, he had the big year in 1995-96, but he faltered badly down the stretch. For whatever reason, playing with Lafontaine brought out the best in Mogilny. The Mogilny of 1992-93 was the Mogilny we should have seen year-in, year-out. I've long maintained that he had the potential to be the next Lafleur: the gifted, dynamic, total offensive weapon who could completely alter the complexion of a game, or the course of a team's season. Mogilny had Lafleur's natural ability, but Mogilny didn't have Lafleur's flair or passion for the game. Mogilny is an incredibly intelligent human being, but he is a flake and a waif. But not in 1992-93.
As the footnote, Lafontaine had one more great solo show left in him, in 1995-96, when he nearly scored at a 100-point clip, when teams could key on Lafontaine, or they could key on Randy Burridge, Derek Plante and Jason Dawe.
The other footnote is that the Islanders became a pretty good offensive team after Lafontaine left. They acquired Turgeon and Benoit Hogue in the deal. They landed Steve Thomas in a separate deal. Pat Flatley managed to stay healthy. Once. And King rounded into form. It's not Mogilny, Hawerchuk and Andreychuk on a PP, but it's still vastly superior talent compared to Lafontaine's cry for help after the 1991 all-star break.
Despite the lack of supporting cast for much of his career, Lafontaine still averaged roughly 45 goals per year in the eight years when he was healthy from 1986-87 to 1995-96. And once he had a supporting cast, the assist totals soared. When Mogilny believed that he had a centre worth of his enormous skill, Mogilny couldn't be stopped, either.
